Reuters reports that publishers are noticing an upswing in sales figures thanks to the controversial Google Book project. Oxford University Press online sales director Colleen Scollans says that sales increases have been "significant", and that "Google Book Search has helped us turn searchers into consumers." Springer has also reported increases in sales, while Penguin told Reuters they have "found greater success from other partnerships," citing Amazon's "Search Inside" program.
Of course, some publishers are still suing Google for their library digitization project.
